JOSEP# Josa wwi Patented May 2 UNITED" mms PATENT OFFICE :remix sosaor This invention -relateslto the method of making hinges, 'and particularly to the manufacture of hinge' butts of the covered joint type including a curved'hood portion at one end of the butt and side walls for the curved hood portion integral therewith -and with the attaching plate of the butt; and the object of the'in'vention is to rovide a novel methodof forming the 'wor pieces or strips from which hinge butts having curved hood portions at one end are adapted to be formed,

and particularly in formin from the strips 'or workpieces pairs of simlar hinge butts;

a further object being to provide strips or,

workpieces in'the. manufacture of v hinge butts ofthe class specified, including means for forming side flange walls to the-attaching plate portion of the hinge butt; and with these and other' objects in view, the invention consists in a method of manufacturing hinge butts more fully hereinafte'r described and-claimed.

e The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Fig; 1 is. a longitudinal, sectional view through a hinge butt made according to my .invention. a F Fig. 2 is a face view of the butt shown in g. 4 p I Fig. 3 shows one step in forming a pair of hinge butts from a stripor workpiece.

y Fig.'4 shows a further step in the method ;of forming the hingebitts. 4

I Fig. 5 is a plan view of one form of strp Y or workpiece which .I. employ.

Fig. 6 is a 'side' edge view'of the structure shown in Fig. 5.

Fig. 7 is a view similar to Fig. 6 showing only a part of the con'struction and showing a modification.

Fig. 8 is a plan view. of the strip shown in Fig. 7; and,

Fig. 9 isa side edge view of a hinge butt made from the strip or workpiece shown in Fi 7. i Figs. 1 and 2 of the drawing, I have ;ofthe butt.

shown one form of hinge butt made accordmg to my invention. In said figure, 10 re resents the attaching plate portion of the butt, 11 the curved hood portion terminating in a stop shoulder 12, said hood portion having comparatively thck side walls 13 enclosigtg the sides of the curved hood portion, said walls formin pintle bearings or the pintle pin of a hinge and having -apertures 14 for such pins. The structure shown in Fig. 9 diflers from that shown in Figs. 1 and 2 simply in 'the addition of side flange walls 15, which are integral with the side edges of the attaching plate portion 10 and with the walls 13, it being understood that the thickness of the flan e walls 15 is preferably considerably less t an the thickness of the walls 13.

In carrying my improved method into effect, I provide an elongated, strip-like body or workpiece 16 which may be formed by a rol-ling process in rollin the stock at the mills, or by the use of sutable forming dies so as to provide on predetermined spaced sections or areas of the strip or workpiece, adjacent semi-circular depressions 11a which partially form the curved hoodportion 11 in the process of forming the hinge butt. At each 'side of the depressions 11& are formed comparatively heavy wall portions 13a 30 which provide the metal in forming the side walls or bearin 13 atthe hood end portion he section '17 intermediate the depremions forms a coupling or binding -flange which supports the. pair of butts to- 35 gether in the process'of forming a pair of' hinge buttsinone die forming operation as later described. These connecting sections are severed and removed in forming the' independent butts of each pair.

V It will be noted upon a consideration of Fig. `6 of the drawing, that the wall por- 'tions 13a are raised wth respect to the upper face of the longitudinal plane of the strip, thus providing 'suflicient metal in 'the strip or workpiece to facilitate the forma-r tion of the wide bearings 13 of the resulting hinge butt. v

The strip or workpiece shownin Figs. 5 e

and`6 is designed primarily for making butts similar to that shown in Figs. 1 and 2 and in the steps of operation indicated in Figs.

- 3 and 4. But, in producing hinge butts such 9, a stripsimilar to that' as'shown in Fi and 8 is employech This shown in F igs.

- strip difl'ers from the strip shown in Figs.

which may be subdivided into independent 5 and 6 simply in the addition of flanged walls 150, at the sides of the strip 'and extendin from the wall portions l3a. Otherwise, e strip shownin Figs: 7 and 8 is identical withtha't shown in Figs. 5 and 6.

After-obtaining the .strip or workpieccs parts suitable for forning one-pair' fhinge -ing the attached plate portions of the finished hinge butt. The result of this forming operation is substantially illustrate d in Fig.

'3 of the drawing, and will be performed by the use of suitable dies;

In this operation, the partial shaping of the hoodportion as well as the side walls may be performed, after which the workpiece may be fashioned bythe use of suitable dies to upset the side walls 1311 of the strip to a finished size, in which operation, the metal of the wall po'rtions 13a, is compacted to form comparatively wide wall or hearing portions 13 of the butt. At the same time, the hood portions 11a are fashioned to the finished size and form represented'in the resulting butt as shown in Fi 1 and 2. i

fiter 'the workpiece has been fashioned in the manner shown in Fig. 4, the joining or coupling section or fin 17 is severed, thus forming two similar butt 'parts with hood portions at one end thereof similar to the butt shown in Figs. 1 and 2. These butts are finished in the usnal manner and the pintle holes 14 are drilled or otherwise formed in the walls or bearings 13.

It will be understood th'at I may 'also make my improved hinges from' the strips or workpieces disclosed, in a'single operation. In other words, the strip as shown in Figs. 5 and or that shown in Figs. 7 and 8 may be fashioned to produce the result shown iniFig. 4 in one forning operation in 'the production of the hinge butts shown in Figs. 1 and 2 and Fig. 9, eliminating the intermediate operation of partial forming indicated in Fig. 3 of the drawing. It wll be further understood that the formation of my' hinge in accordance With the method herein set forth may be made under the hot or cold process as maybe desired, depending largely upon the character of the resulting product or hinge butt,

it being preferable to use the hot process when comparatively heavy walls are employed in the bearing 13.- V It will be understood that my invention is not limited to the specific shape and contour of the strips or workpieces herein disclos'ed, as these strips are merely suggestions as to the general form and structurepf a 76 strip or workpicce which nay be used in the manufacture of hnges of the class under consderaton m accodancewith my `et`hod` M butts, or used in the form of a continuous The distinctive feature of the invention 'esides in the provision of an elongated preforned strip or workpiecehaving adjacently arranged curved r'ecesssor dep'es sionsjoined by a connecting fin, said depressions being spaced longitudinally of the workpiece, thereby facilitating the formation of the strip or workpiece in the manner herein set forth, obviating the necessity of using a plain bar or sheet which must be partially formed or blanked, and then afterwards passed through the several shaping and forming Operations which may be necessary in the production of the resulting product.

While a slight additional cost would result from the formation of the 'particular 'strips or workpieces herein' disclosed, this added cost would be slight as Compared with the cost of blanking and shaping other workpieces in accordance with known processes. Various other changes in and modifications of the method herein shown and described may be made 'within thewscope of the a pended clains, without departing. from t e spirit of my invention or sacrificing its advantages.
